Patent DE-3127298-A1 (DE)
Title: Method of dividing wide metal strips
Inventor: MERZWEILER HORST
IPC: B23D19/06
Filed: 1981-07-10
Abstract: The invention relates to the longitudinal dividing of wide metal strips to form narrow strips with periodically recurring circular-arc-shaped outer contours as an intermediate shape for the production of circular blanks or workpieces. The aim is to produce various circular-arc shapes with one tool set. Due to the periodically alternating outer contours of the longitudinally divided strips, optimum material utilisation of the wide strips for specific blank shapes is possible. According to the invention, the object is achieved in that the desired contours are produced and the wide strips separated into individual narrow strips in two steps. In the first operation, grooves which have the contours of the sectional strips are pressed into the material by means of pivotable and transversely displaceable discs with a wedge-shaped cutting angle which are arranged above a smooth supporting roller. In the second operation, the sectional strips are completely separated at the predetermined breaking points in a tear-off device and are then coiled. The invention can be used where circular blanks are to be produced and processed automatically in larger quantities and in a material-saving manner. <IMAGE>
Patent DE-3127751-A1 (DE)
Inventor: SCHLEPPINGHOFF BERNHARD DR
IPC: C10G45/32
Filed: 1981-07-14
Abstract: Unsaturated hydrocarbons and mixtures in which the latter are present are treated with anion exchangers prior to hydrogenation and are then hydrogenated catalytically in a known manner. The treatment with anion exchangers is carried out at 0 DEG -120 DEG  C. and at a space velocity of 0.1 to 10 l of hydrocarbons to be hydrogenated per l of exchanger, per hour. The process avoids other, energy-intensive pretreatments, for example distillation of the hydrocarbons to be hydrogenated, or washing, and can be carried out in simple equipment. A considerable prolongation of the catalyst operating time is achieved in the subsequent catalytic hydrogenation.

Title: Fastening a structural part on a wall, in particular on a vehicle
Inventor: ERCK KARL ING GRAD
IPC: B60R13/04
Filed: 1981-08-26
Abstract: The invention relates to the fastening, shown in Figure 1 by way of example, of a structural part (12) on a wall (15) in the region of an elastic profiled strip (5), fastened thereon, in particular on a vehicle. The structural part (12), projecting, with its overall height, beyond the profiled strip (5), catches, by means of a continuation (11) located in one (13) of its two end regions (13, 17), in a slot (7) in the profiled strip (5) and is fastened, by means of the other end region (17), on the wall (15). In order to allow for temperature-related changes in length between the structural part (12) and the wall (15) and thus to avoid thermal stresses, the invention proposes to use a permanently plastic adhesive composition (18) to fasten the other end region (17) on the wall (15). Furthermore, the catching portion (10) is to be configured such that, owing to its elasticity, the profiled strip (5) permanently transmits a moment to the structural part (12) such that its other end region (17) is constantly pressed against the adhesive composition (18). <IMAGE>

Title: Polyurethane compositions for hollow fibre dialysers
Inventor: NEUMANN GERT DIPL CHEM DR RER
IPC: A61M1/20
Filed: 1981-12-14
Abstract: The invention relates to polyurethane compositions for hollow fibre dialysers, which compositions comprise polyisocyanates and homogeneous, storage-stable polyol mixtures based on castor oil as the principal constituent, a proportion, which can be varied within broad limits and essentially determines the mechanical properties, such as hardness and elasticity, of the cured polyurethane, of low-molecular-weight, polyfunctional, hydroxyl-containing compounds which are usually virtually incompatible or only slightly compatible with castor oil at room temperature, and a solubiliser in the form of partial esters of the low-molecular-weight, polyfunctional hydroxyl compounds with carboxylic acids having a carbon chain length of greater than 14, and optionally a small amount of activated zeolite. The curing of the polyurethane compositions, which are in principle suitable as materials in medical technology, but in particular as embedding materials for cellulose hollow fibres in dialysers, is advantageously carried out, without impairing the dialysis properties and geometry of the hollow fibres, in the presence of tin/sulphur compounds as catalyst at temperatures between 20 and 80 DEG C, preferably up to 65 DEG C. The cured polyurethane compositions have a physiological acceptability which means the medical purity requirements laid down in pharmacopoeias. The hollow fibre dialysers produced using the polyurethane compositions according to the invention are suitable for haemodialysis.

Patent DE-3222873-A1 (DE)
Title: Concrete formwork having formwork-panel and binding-piece joints
Inventor: KNOP GUENTER
IPC: E04G17/14
Filed: 1982-06-18
Abstract: The invention relates to a concrete formwork having large-area formwork panels comprising formwork board, formwork girders, consisting of top and bottom booms and openings in the webs, and binding pieces comprising profiled boom girders. At each crossing point of formwork girder and boom girder, boards having recesses adapted to the boom girders are fitted on both sides of the web, so that on bracing the boom girders by means of a bracing member, positive-locking is brought about between boom girder and formwork girder. As a result of the displaceability of the boom girders in their longitudinal direction, in the unbraced state, the boom joint can be offset with respect to the formwork-board joint, so that a strapped formwork-panel joint with flush formwork boards results, and also as a result of the fact that formwork-panel edge girders possess in the bottom boom a longitudinal groove into which flat pieces with a hammer head and wedge engage, the wedge, when it is driven in, causing the formwork-panel edges to be brought up against the binding pieces in a precisely fitting manner. Special sliding pieces of Z-shaped configuration are suspended from the flange of the boom girders and form an abutment for formwork anchors and similar auxiliary means. Using angular anchoring pieces, which are inserted into circular openings in the boom girders, the formwork panels can be clamped together at any desired angle around the axis of the circular opening in the boom girder, so that the formwork boards are also brought together in crunching fashion in the joint.

Patent DE-3236830-A1 (DE)
Inventor: YABE HIROSHI
IPC: G10L25/78
Filed: 1982-10-05
Abstract: An electronic timepiece with voice memory includes an auto start circuit which senses the presence of an input voice and automatically controls the start of recording. Voices inputted from the outside are coded and the coded data is stored in memory. An output means reads out the memory contents and transforms the coded contents into an analog voice signal. When the incoming voice exceeds a predetermined level, the recording means is automatically started by an output from a level detector. Memory is divided into at least two regions. The first region stores coded voice data before the auto-start circuit operates and later coded voice data is recorded in the second region after the autostart circuit operates so that the initial portions of speech are not lost.

Title: Method for the computer-controlled monitoring of screw connections
Inventor: WINKLER WOLFGANG
IPC: G01L5/24
Filed: 1982-10-14
Abstract: A method for the computer-controlled monitoring of screw connections by measuring the torque or rotary-angle profile against time or the torque profile against the rotary angle beyond the moment of applying a maximum tightening torque and by determining the area which is enclosed under the corresponding curve piece with the time axis or rotary-angle axis. The size of this area is a measure of the correct tightening of a screw connection. Large values result if the cap-screw bearing surface and workpiece surface are not frictionally connected, so that, as a result of elastic torsion of the screw shank, a restoring moment resulting from this appears at the screw spindle.

Title: Open-jaw spanner with rotating-ring mechanism
Inventor: MEISS PETER
IPC: B25B13/10
Filed: 1982-11-30
Abstract: The open-jaw spanner with rotating-ring mechanism (ORM) is a tool for tightening and loosening nuts without having to be removed during the operation. The range of application of the hitherto known ratchet spanners is extended by the ORM to all imaginable areas of application. Wherever it was hitherto necessary to work with a simple open-jaw spanner, whether in locations which are difficult to get at or in the case of long screw threads, or in the case of pipes which are screwed together, it is now possible to work more quickly and efficiently. The ORM is of course also usable where a ratchet spanner has hitherto been used. The ORM is designed in such a way that it is able, by using two drive segments which advance an open rotating ring with integrated insert holder, to overcome the opening present in the open-jaw spanner. In this process, one of the drive segments is always in contact with the rotating ring. <IMAGE>

Title: Fast positioning pick=up system for optical play-back appts.
Inventor: KIMURA SHUCHI
IPC: G11B7/085
Filed: 1983-01-13
Abstract: The appts. has a circuit to generate a track jumping signal (SJJ), consisting of a driving impulse signal (SDD), followed by a braking impulse signal (SBB). Generation of this signal, which is delivered to a control signal generating circuit (22), so as to move the scanner rapidly to a desired position, depends on a tracking error signal (SE) delivered by a tracking error signal generator (11). The duration of the driving impulse signal and of the braking impulse signal are regulated by counters (26,27) connected to the input of the control signal generating circuit. Pref. a system control circuit (21) generates an initial instruction signal (SX) corresponding to the start of a search procedure, while one counter (26) generates a second instruction signal (Sy) corresponding to the end of the driving impulse signal. A signal (Sz) corresponding to the end of the braking impulse signal is generated by the second counter (27).
